How Team Interlock Ecosystems Shape the Assembly of Scientific Teams: A Hypergraph Approach

ABSTRACT

Today’s most pressing scientific problems necessitate scientific teamwork; the increasing complexity and specialization of knowledge render “lone geniuses” ill-equipped to make high-impact scientific breakthroughs. Social network research has begun to explore the factors that promote the assembly of scientific teams. However, this work has been limited by network approaches centered conceptually and analytically on “nodes as people,” or “nodes as teams.” In this article, we develop a “team-interlock ecosystem” conceptualization of collaborative environments within which new scientific teams, or other creative team-based enterprises, assemble. Team interlock ecosystems comprise teams linked to one another through overlapping memberships and/or overlapping knowledge domains. They depict teams, people, and knowledge sets as nodes, and thus, present both conceptual advantages as well as methodological challenges. Conceptually, team interlock ecosystems invite novel questions about how the structural characteristics of embedding ecosystems serve as the primordial soup from which new teams assemble. Methodologically, however, studying ecosystems requires the use of more advanced analytics that correspond to the inherently multilevel phenomenon of scientists nested within multiple teams. To address these methodological challenges, we advance the use of hypergraph methodologies combined with bibliometric data and simulation-based approaches to test hypotheses related to the ecosystem drivers of team assembly.     

Imagination and Narrative: Young People’s Experiences

Imagery generation in dramatized audio drama is still poorly understood with the majority of work having been done from a radio advertising perspective. This study sought to understand audio drama imagery generation by using teenage listeners. The study demonstrated that teenagers can follow purely auditory narrative with ease and can generate unique and vivid imagery through aural dramatic stimulation. The study also showed that listening in the dark and as a group are appealing for audiences.     

The Subtitle Effect: How Subtitle-Facilitated Perceptual Learning Can Make Subtitles (Seem) Less Necessary

In television and film production, speakers whose accents are judged difficult to understand are often subtitled, but viewers may question such judgments if they later perceive the subtitles as unnecessary. Such doubts can be ill founded, however. We report two experiments showing that the presence of bimodal subtitles (subtitles in the same language as the audio) on a given video clip can make subtitles seem less necessary for that clip and can improve comprehension of a second, unsubtitled clip of the same speaker. This, we argue, is because bimodal subtitles provide alternate access to the lexical information in the audio, thus facilitating perceptual learning of the subtitled speaker’s accent. This perceptual learning, through which listeners adjust their sound–phoneme mappings to accommodate the unfamiliar phoneme realizations underlying the speaker’s accent, can quickly make subtitles less necessary, potentially creating the illusion that they were never necessary—a phenomenon we call the “subtitle effect.”     

Children's algorithms as schemes

Arithmetical knowledge is viewed as simply the coordinated schemes of actions and operations the child has constructed at a particular point in time. A fundamental distinction is drawn between operative and figurative schemes in the context of additive schemes. Numerical extension, an operative scheme, is distinguished from intuitive extension, a figurative scheme. The basis of the distinction resides in (1) the anticipatory nature of the schemes, (2) the adaptability of the schemes, and (3) the nature of the concepts which serve as a basis for what triggers the schemes. This fundamental distinction is crucial in the mathematical instruction of the child for the child necessarily has to construct his or her own mathematical reality even if that reality eventually becomes compatible with the reality of the social group in which the child has to operate.     

Occupations of Indonesian graduates

Despite a considerable increase in the number of graduates in Indonesia, they still remain a minute fraction of the labour force. The majority are in the professional, administrative, and clerical occupations, and employed by the state mostly in a civilian, some in a military, capacity. Ever larger numbers of the available graduates have been moving into state employment. The occupations mentioned are also the most highly paid, with the administrative far ahead of the professional and clerical.The largest group of graduates had qualified in law, the social sciences, arts and sciences; the next largest in teaching. Health, agriculture, and the technological subjects of engineering and communications had attracted only a relatively small proportion.Not more than half of the graduates were in occupations for which their studies were specifically relevant, and holders of the Bachelor (Sarjana Muda) degree were less likely than Masters (Sarjana) to be so employed. The largest proportion of graduates in related occupations had qualified in teaching and health, while the smallest had studied law, the social sciences, arts, and sciences, a few more the vocational subjects of agriculture and engineering. Selection for senior positions appears as important as training for specific occupations.Teaching and health were also the two subjects with the highest proportion of graduates among the professionals. However, they were not particularly well represented among the better-paid administratives. Here, graduates in agriculture, engineering and the law, the social sciences, arts and sciences were much better favoured.Some occupations show a certain concentration of graduates in specific subjects; in particular, half of the graduates in the professional group were trained as teachers. However, no occupation is the preserve of any one subject.There were more Bachelor than Master graduates in all groups except the professional and administrative, where the reverse was the case. One may conclude that both these groups gave a certain preference to Masters, and were in turn the targets of those so qualified.     

Christian ethos secondary schools,parental church attendance and student attitude towards Christianity: exploring connections in England and Wales

ABSTRACT

This study employs multi-level linear statistical modelling to examine the power of school-level and individual-level factors to predict individual differences in scores recorded on the Francis Scale of Attitude toward Christianity by 6,036 students (who self-identified as either Christian or no religion) in year-seven, year-eight, year-nine, year-ten, and year-eleven classes within 10 Christian ethos secondary schools. The data demonstrate the complex relationships between school admission policies, parental church attendance (PCA), and the students’ age and sex. Overall PCA emerges as a decisive factor in promoting a positive attitude toward Christianity among students. Christian ethos schools may wish to give greater attention to the importance of parental religiosity in maintaining the Christian ethos of these schools.
